Using Timelines to Manage Application States

Hi,

I try to figure this out for the last 3 days but I can't get it to work. I make the movie clip, drag it on level0 , it work with one button, I get the rollover, rollout, active, but I can't get it to work with multiple buttons. Can anybody tell me what I 'm doing wrong or how to make it work with more than one button

here is the url:
